WINDOW-SHADE ADJUSTER.

Specification of Letters Patent.

Patented Sept. 16,1913.

Application filed May 17,1909. Serial No. 496,641.

To (ZZZ whom it may concern:

Be it known that I, WIRT Boron, a citizen of the United States, residingat the city of Chicago, in the county of Cook and State of Illinois,have invented a new and useful Improvement in Window-Shade Adjusters, ofwhich the following is a specification.

My invention relates to devices for changing the vertical position ofwindow shade rollers and adjusting them at any desired distance from thetop of the window.

It is highly desirable, especially in living rooms and sleepingapartments, to obtain ventilation from the top by lowering the uppersash, but when the shades are hung on stationary brackets, according tothe usual custom, at the top of the casings they interfere with the aircurrents, are whipped about and injured thereby, or must be rolledtightly, leaving the window entirely unshaded.

It is the object of my invention to permit the shade roller itself to belowered to clear the opening created by lowering the sash, while at thesame time curtaining the lower part of the window as desired. Somedevices with this end in view have been made, but they have beencomparatively heavy, expensive and cumbersome, and usually have requiredspecial fitting of the shade rollers and shades.

My present inventionis simple and inex-. pensive, it is easily appliedwithout shortening or other modification of the shade roller or shadesas already hung; injury to the shades when operated is guarded againstand the lower part of the window completely curtained, while permittingfree access, light or air from the upper part as may be desired.

The principles of my invention are illustrated in the drawings, inwhich- Figure 1 is an inside view of a window, provided with my device.Fig. 2 is a vertical section of the same on the'line 2-2 of Fig. 1. Fig.3 is an enlarged detail of a bracket and a portion of the backet guide.

Further describing my invention: 1 is the casing of a window providedwith a shade 2 mounted on the roller 3. Inside the window casing uponthe stop is placed a bracket guide or runway 4:. The latter in sectionshould be somewhat that of a shallow U having outturned edges 5. Achannel 6 is thus provided between the vertical walls 7 of the runway.Two brackets 8, as illustrated in Fig. 3, are provided. These bracketsare provided on each side and at either end with wing pieces 9 which areturned downwardly and inwardly so as form grooves within which run theout-turned edges of the channel pieces or guideways. A wing 10 should beformed on the bracket provided with the opening 11 by which a suspendingcord may be attached, and a similar piece 12 at the lower end provides acheck to engage a stop at the lower end of the guideway. Two of thedescribed channel pieces should be placed at the upper part of thewindow within the stops. The bracket shown in Fig. 3, has a rectangularopening to take the non-revoluble shaft of an ordinary spring roller.The other should have a circular opening to take the revolving axis atthe opposite end of the roller. I prefer to make the brackets asillustrated with edges 8 extended across and over the channels. Thecurtain roll is thus protected, and the brackets tend to guide thecurtain as it is rolled thereon. The lower end of the runways should besecured to the casing with a screw 12 which projects sutficiently toengage the stop 12 and prevent the brackets from leaving the lower endof the guide. The upper portion of such guide should have a perforationthrough which a securing device may be passed into the casing, saiddevice being adapted to engage with the wing or stop 10 and providedwith a loop through which a cord may be passed. One cord 13 is passedthrough the loop 14 and secured to the right hand bracket. Another cord15 is secured to the left hand bracket, passed through the loop 16, andalso through the loop 14, at a little distance below which it shouldpreferably be knotted to the cord 13. Both cords then extend down theinside of the window where they are attached to a hook 17. Theadjustments of the parts to the window frame may be made after removinga shade when fitted thereto in the ordinary manner. hen the parts areplaced as described, one trunnion of the roller is placed in theappropriate opening in one bracket and the other bracket is raised toallow the other trunnion to be inserted therein. The bracket is thendropped and the adjustment is complete. It will be seen that the channelof the runway provides a space adapted to take the trunnions of anordinary window shade roller, whereby free movement up and down ispermitted. The same channel provides clearance for the cord attachinglip and stop 10 and the lower stop 12.

I claim:

In a window shade adjuster, stationary channel-shaped guides secured tothe window casing and provided with outwardly turned flanged edges,brackets slidable on said guides restrainingly engaging said sides, eachbracket comprising an apertured plate having its ends provided Withinwardly turned lips receiving the outwardly turned edges of the guidetherein, said plate having side projections extending beyond the guidesand constituting means to guide the shade in the winding and unwindingthereof on its roller, an inwardly-eXtending stop at each end of eachbracket projecting into the channel of the guide, and supporting meansin the form of cords attached to the lugs of said brackets. In witnesswhereof, I have hereunto set my hand, this 14th day of May, A. D. 1909,in the presence of two subscribing witnesses. WIRT B. BOYCE.
